Lubricants and Centralized Lubrication Systems 

Centralized lubrication systems may only be used for their intended 

purpose. Centralized lubrication systems can normally be operated 

with the lubricants listed in the system’s documentation as long as 

the latter comply with the respective consistency classes and viscosity 

limits within the indicated temperature range. It is possible for the 

demands on a lubrication system’s configuration to vary concerning 

the lubricant and the use to which the installation is put. 

Given the already high “apparent viscosity”, we advise against the 

use of grease conforming to NLGI Grade 0 since it is possible for fundamental 

properties related to delivery of the lubricant to deteriorate 

considerably, particularly at low ambient temperatures. 

If, nevertheless, a lubricant conforming to NLGI Grade 0 is required, 

we recommend that its properties be checked to confirm they are 

adequate. 

Suitable Lubricants 

The lubricants must be suitable for the lubrication of bearings under 

the ambient conditions to be expected in operation. Our experience 

shows that suiteable lubricants are available from every well-known 

manufacturer. Please contact the supplier when you choose a 

lubricant. SKF Lubrication Systems offers to test the deliverability 

of a selected lubricant in the event of doubt. Lubricants that meet 

the identical specifications of SKF Lubrication Systems Germany AG, 

Daimler AG and MAN AG match each other in terms of the parameters 

applying to their deliverability.

f) Installation 

(Detailed installation instructions are 

available on request.) 

This information is supposed to be a 

guide line and aid for the fitter. It will 

enable him to install the equipment 

on vehicles even if there are no tubing 

layouts available, or only incomplete ones. 

For the prevalent, standard types of 

commercial vehicles, we have prepared 

tubing layouts that show how the installations 

are supposed to be done. 

If required, these layouts will be mailed 

free of charge. 

Additional superstructures and special 

vehicles can be outfitted on the basis of 

these layouts. 

The preassembled VKSO distributors for 

standard systems are supplied with a 

preset metered quantity, but they can be 

changed to another quantity of lubricant 

if necessary. 

Install the VKSO distributors at suitable 

locations on the vehicle and connect to 

the tubing. 

Max. length of the secondary lines is 6 m 

(connection: distributor – lubrication point). 

Tighten the socket unions, but do not 

overtighten (maximum of 1 1 /2 turns). 

The tapered sleeves and tubing are 

slightly deformed when tightened, thus 

offering no resistance as a fixing bolt 

would when tightened. 

Attention must be paid to the following 

when installing the secondary lines: 

– Steering lock angle, sagging, chafing 

spots. 

– Keep away from heat sources. 

Install the pump and control unit at a 

suitable place. 

Connect hoses and make electrical 

connections. 

Some installation hints: 

– Use the existing holes drilled in the 

chassis and in other vehicle parts for 

the installation. 

– Span large boreholes with body washers. 

– Lay 4 x 0.85 plastic tubing (as per 

WVN716, flexible) between distributors 

and lubrication points. 

– Use 734...-K hose lines to connect 

nonstationary lubrication points and 

lubrication points that are subject to 

heavy mechanical stress and strain. 

– The compressed air for the PEF-90 

pneumatically actuated pump must 

be taken from a line for auxiliary loads. 

The regulations of the german TÜV 

(Technical Control Board) must be 

observed. 

– The pertinent Hazardous Goods Road 

Ordinance Germany (GGVS) must be 

observed in the case of tank trucks 

and other vehicles carrying hazardous 

goods. 

The following pump unit can be used: 

electrically operated gear pump units 

KFU2-40, KFU6-20 in conjunction with 

cable harness 997-000-374; compact 

units KFB(S) in conjunction with cable 

harness 997-000-630 or 997-000-650. 

Furthermore, the pressure switch line 

must likewise be laid in corrugated tubing 

2. Operation and maintenance 

In the case of automatically controlled 

systems, with the exception of KFB(S) 

compact units, the indicator light goes 

on for about 3 seconds every time the 

ignition is switched on. (See 3.a for malfunctions 

of indicator light.) 

For the most part, maintenance is limited 

to topping up with clean lubricantwhen 

necessary. 

All tube connections should be checked for 

a tight fit when the vehicle is inspected. 

Replace torn or worn hose lines after 

eliminating the cause of the problem, 

and trigger test lubrication. Actuate automatic 

systems by hand and observe the 

indicator light. 

The main line (connection: pump – 

distributor) is monitored by a pressure 

switch that reports the build-up of 

pressure. Exception: KFBS and KFUS 

units. If the indicator light does not light 

up, or if it burns constantly in the case 

of automatic systems, this means the 

pressure has failed to build up. 

Select a smaller metered quantity for 

highly overlubricated points and a higher 

quantity for dry points. 

If the entire system is overlubricated or 

underlubricated, there can be malfunction: 

in this case, follow the instructions in 3.b 

or 3.c below. 

3. Malfunctions and their elimination 

a) Fault indication by indicator light. 

The indicator light does not go out about 

3 seconds after the ignition is switched 

on or the motor has been started. 

Check lubricant level in the reservoir; 

top up lubricant if necessary and bleed the 

system. 

In the case of electrically operated gear 

pumps, loosen the screw union of the 

main line while the pump is running. 

There must be a continuous discharge of 

lubricant. 

In the case of pneumatically operated 

systems: 

Check the compressed air supply. 

Minimum pressure is 6 bars. 

Check pump function. 

The piston stroke must be heard or felt 

when compressed air is applied. 

Check pressure in main line. 

Loosen the lubrication-point connection 

and check whether the distributor is 

delivering lubricant. If it is, the fault must 

be looked for in the pressure switch, 

electrical wiring or control unit. 

10 1-9420-EN


Please note: 

The distributor will not feed lubricant until 

the main line is relieved of pressure again. It 

is therefore called a “relubrication distributor”. 

Check electrical connections: 

Is power available? 

Are all terminals tight? 

Check the indicator light, solenoid valve, 

pressure switch and control unit. 

Main line connections, main hose lines in 

particular, must be checked for leakage. Then 

check whether the pump valves are dirty. 

1-9420-EN 

b) Entire system insufficiently lubricated. 

Install a pressure gauge in the main line 

and check the pressure build-up and 

relief. Min. pressure build-up is 30 bars. 

A maximum residual pressure of 1 bar 

may remain after the pressure is relieved 

(measured at pump‘s outlet port). 

c) Entire system is overlubricated. 

Check setting of control unit and increase 

interval time if necessary. 

d) Individual lubrication points are overlubricated 

or underlubricated. 

Change metered quantity. 

e) Distributor faults. 

Replace distributors. 

Please note! 

A high level of cleanliness must be maintained 

when doing any work on the system, 

es pecially when replacing metering nipples 

on distributors. Dirt in the system causes 

malfunctions. 

Never use trichloroethylene, perchloroethylene 

or similar liquids aggressive to 

Perbunan when cleaning centralized lubrication 

systems. Suitable cleaning agents are 

petroleum ether or kerosene. 

Pressure curve in main line in the case of systems with VKSO relubrication distributors 

Pneumatically actuated piston pumps and 

electrically operated gear pump units have 

an identical pressure curve, but the time 

required for the pressure build-up will generally 

be shorter with pneumatically actuated 

piston pumps. 

The maximum pressure reached in the main 

line depends on the actuating pressure of the 

piston pumps or on the pressure intensity 

of the safety valve in the case of gear pump 

units. 

Pneumatically actuated

Functional sequence 

At the end of the preset interval time, the 

pump motor is switched on and the pressure 

required by the system built up. This is reported 

to the control unit by the actuation of 

the pressure switch. At the end of the pump 

running time, the pump motor is switched off 

and a new interval time begins. 

�� 

�� 

If there is no signal from the pressure switch 

while the pump is in operation, the control 

unit will report a fault at the end of the pump 

running time. This is signaled by the constant 

burning of the indicator light. 

The metering chambers of the distributors 

are filled with lubricant during the pressure 

build-up in the main line. 

�� 

�� 

�� 

�� 

�� 

�� 

The relief of pressure in the main line via the 

pressure relief valve starts when the pump is 

switched off. The lubricant from the metering 

chambers is delivered to the lubrication 

points by the spring-loaded distributor 

pistons at the same time as the pressure is 

relieved. 

The KFB(S) compact units have the same 

functional sequence, but the pressure buildup 

is not monitored in this case.

Gear pump units KFU2-40, KFU6-20, KFUS2-64 

with reservoir, electrically operated 

The gear pump unit consists mainly of a 

gear pump with relief valve, safety valve, DC 

motor, transparent lubricant reservoir, filler 

socket and angle bracket. The DC motor and 

filler socket are covered by a hood to protect 

them from dirt. The hood snaps into place on 

both sides of the reservoir lid. 

Function 

The gear pump continuously supplies lubricant 

to the relubrication distributors via the 

main line network when the pump is in operation. 

As soon as the metering chambers of 

the distributors are full, the excess lubricant 

flows back into the reservoir via 

the safety valve.

*) This unit should only be used for systems with a minimum lubricant 

consumption of 6 l/year. 

At the end of the pump running time (start 

of the interval time), the pressure relief valve 

opens so that the pressure in the main line 

can drop to a residual pressure of 0.2 to 1.0 

bar. The spring-loaded pistons of the distributors 

can now deliver lubricant from the 

metering chambers to the lubrication points. 

Nearly every size of system on commercial 

vehicles, including superstructures, can be 

supplied by one single pump when a KFU2- 

40 or KFU6-20 pump unit is used. 

Furthermore, the semitrailer or trailer can be 

connected using an interconnected system, 

but this is only advisable when the motor vehicle 

and semitrailer/trailer are 

rarely or never disconnected from each other.

Piston pump PEF-90, pneumatically actuated 

The unit consists mainly of 

– a lubricant pump in the form of a 

pneumatically actuated piston pump with 

spring reset, 

– suction valve, 

– combination pressure and relief valve, 

– lubricant 

reservoir in the form of a bellows, 

including protective holder, 

– filler socket for topping up the lubricant 

reservoir. 

Function 

The delivery piston is moved in the direction 

of the outlet after pressurization with compressed 

air. As a result, the lubricant that 

flowed into the pump chamber through the 

suction valve is delivered to the system via 

the combination pressure and relief valve. 


1-9420-EN 

After the compressed air is switched off, the 

delivery piston is returned to its initial position 

by the reset spring. Due to the resulting 

underpressure, the combination pressure 

and relief valves also return to their initial 

position, thereby opening the pressure relief 

bore; the pressure in the main line is relieved 

as a result. 

Due to the pressure relief, the paths from the 

metering chambers to the friction point are 

opened in the distributors so that the springloaded 

metering pistons can now deliver 

lubricant to the friction point. 

The inlet valve is opened by the underpressure 

resulting from the return motion of the piston, 

and new lubricant flows into the pump 

chamber. 

This ends the work cycle.

value (in hours) programmed for PAUSE 

(tPA). 

PAUSE (pump OFF) with counter function 

– programmable from 1 to 999 pulses 


cPA (c = counter, PA = PAUSE) 

The PAUSE (the interval between two lube 

cycles) is determined by the interval between 

the time signals arrive at the counter input 

and by the value programmed for PAUSE 

(cPA). 

CONTACT (pump ON) with timer function 

– programmable from 1 to 99.9 minutes 


tCO (t = timer, CO = CONTACT) 

The pump running time (CONTACT) is 

determined by a clock cycle (timer) generated

This monitoring function is intended for 

centralized grease lubrication systems 

designed for NLGI grades 000, 00, 0 in which 

the pressure in the main line is monitored. 

Once the monitoring parameter PS has been 

programmed, the pressure switch installed 

in the main line is monitored for respective 

signals while the pump is in operation. 

CS (Cycle Switch) 

This monitoring function is intended for 

centralized grease lubrication systems with 

progressive feeders in which a piston‘s motion 

is monitored with a cycle switch. 

Once the monitoring parameter CS has been 

set, the cycle switch installed on the progressive 

feeder is monitored for the respective 

signal while the pump is in operation. 

The respective monitoring parameter 

selected (PS or CS) is displayed by the lighting 

of the corresponding LED in the PAUSE 

(interval) mode. 

Without monitoring (OFF) 

The monitoring can also be switched off 

(OFF). 

The control system then works without 

direct monitoring of the pressure build-up in 

the main line or without monitoring of the 

feeder‘s operation. The PS or CS LEDs do 

not light up. 

Fault displays 

The red FAULT LED shows a group fault 

signal when it constantly burns. The cause of 

the fault signal is additionally shown on the 

digital display to help with troubleshooting. 

The following messages are provided for: 

FPS – pressure build-up fault when monitoring 

is effected with a pressure switch. 

FCS – cycle switch fault when a progressive 

feeder is not working or is blocked 

(line break). 

Special functions 

Control units comprising the IG502 group 

have two electronic counters in which times 

are permanently stored; they cannot be 

changed by the user. 

These counters are used to check the operation 

of the centralized lubrication system and 

are read out via the LED display. 

Fault-hours counter 

The amount of time a farm or construction 

machine has been run with a non-functioning 

centralized lubrication system (e.g. with 

no lubricant in the reservoir) is added up by 

the fault-hours counter. 

The counter‘s contents are automatically 

updated and cannot be cleared. The current 

state of the counter can be displayed by invoking 

function parameter Fh on the display 

and operating panel. The current value is 

displayed in hours. 

The counter has a resolution of 0.1 hour, i.e. 

the smallest displayable interval amounts to 

6 minutes. 

Elapsed-hours counter 

The electronic elapsed-hours counter adds 

up the time in which power is applied to the 

control unit. 

The counter‘s contents are automatically updated 

and cannot be cleared. The current 

state of the counter can be displayed by invoking 

function parameter Oh on the display 

and operating panel. The current value is 

displayed in hours. 

The counter has a resolution of 0.1 hour, i.e. 

the smallest displayable interval amounts to 

6 minutes. 

The units meet the legal requirements of 

the applicable EC Directives. 

The unit is EC Type Approved (e1). 

Application 

The IG502-2-E universal control unit is used 

to control and monitor centralized lubrication 

systems on commercial vehicles. The control 

unit‘s functions can be programmed. Its 

housing dimensions, electrical connection 

and functions are compatible with those of 

SKF control units currently in use. 

The operating elements are protected by a 

foil against moisture and dirt. The unit has 

a voltage-independent data memory. This is 

where the configuration data and parameters 

are stored. As a result, the control unit is not 

dependent on a constant supply of voltage. 

If an external indicator light SL has been 

installed in the driver‘s cab, it will light up for 

3 seconds after the unit is switched on. 

Installation 

The unit has to be installed in a closed compartment 

on the vehicle where it is protected 

from ambient influences. It is fastened in 

place with straps. 

The IG502-2-E is accommodated in an IP 20 

type of enclosure. The plug conforms to 

safety class IP 00. 

If the control unit is installed in a hard-toreach 

place, it is advisable to additionally 

install an illuminated pushbutton on the 

dashboard to serve as a fault display and 

function check.

Trailer and semitrailer lubrication 



for use on vehicles carrying hazardous goods 

Functional sequence 

The switching pulses for the stop light are 

registered and added in the electronic control 

unit at an interval of at least one second. 

As soon as the preset number of brake 

applications is reached, the pulse-controlled 

3/2-way solenoid valve is energized for a 

lubricating time of at least 40 seconds, 

thereby pressurizing the compressed air 

cylinder of the piston pump. The delivery 

piston of the pump executes one working 

stroke and the lubricant distributors are filled 

(relubrication distributors). 

Application of the brakes during the lubricating 

time is ignored by the control unit. 

The first application of the brakes at the 

conclusion of the lubricating time reverses 

the valve. As a result, the compressed air 

cylinder of the piston pump is relieved of 

pressure, and the delivery piston returns 

to its initial position. At the same time, this 

relieves the pressure in the main line so that 

the distributors can now deliver the lubricant. 

Further applications of the brakes are now 

registered and added again to the control unit. 

The control unit is equipped with an EEPROM 

memory that stores the counter states, even 

when no power is applied between applications 

of the brakes. 

The number of times the brakes have to be 

applied before lubrication takes place depends 

on the conditions in which the vehicle is 

operated. It is possible to set the number of 

times (20, 40, 60,80, 100, 120, 140, 160, 

180, 200, 220, 240) after which lubrication 

is initiated. After changing the setting, it is 

advisable to trigger manual lubrication so 

that the counter begins at 0 again. 

1-9420-EN 

The unit is set at the factory for 100 applications 

of the brakes before lubrication 

starts. 

A pushbutton is built in for function tests 

when the brakes are applied. The function 

test can only be performed when there is 

adequate air pressure (more than 6 bars) in 

the air tank and power is available.

KFB/KFBS compact unit, electrically operated 

KFBS1 

The KFB/KFBS compact unit consists mainly 

of a gear pump with DC gear motor, relief 

and safety valve, control unit, pushbutton for 

manual triggering, and lubricant reservoir. 

The lubricant reservoir comes with an overfill 

release valve and vent. The filling level 

can be seen in the reservoir that is made of 

transparent material. The reservoir is filled 

via a filler. 

The lubricant supplied by the pump is distributed 

to the individual lubrication points 

via VKSO piston distributors. 

The KFBS pump unit is controlled by the integrated 

IG502-I control and monitoring unit. 

This can be done on a time or (pulse) loaddependent 

basis, with or without monitoring 

of the system‘s pressure build-up. A pressure 

switch 1) has to be installed in the system for 

this purpose. 

1) Pressure switch for 20 bar switching pressure, 

order No. DS-E20-S1 (when installed at end 

of main line); 

for 25 bar switching pressure, 

order No. DS-E25-S1 (not possible when installed 

at end of main line). 

Associated cable harness for pressure switch, 

order No. 997-000-379. 

Function 

The automatic cycle consisting of the interval 

time and pump running time is started after 

the KFB/KFBS unit has been connected to 

the vehicle’s electrical system and the ignition 

turned on. 

When the ignition is on, the pump motor is 

switched on at the end of the interval time and 

the pump running time started. During the 

pump running time, the gear pump delivers 

lubricant from the reservoir to the metering 

chambers of the relubrication distributors. 

As soon as the metering chambers of the 

distributors are full, the surplus lubricant flows 

back into the reservoir via the safety valve. 

Forced pressure relief is initiated at the end of 

the pump running time (beginning of the interval 

time) and the pressure in the distributor 

feed (main line) drops to a residual pressure 

of 0.2 to 1 bar via the open relief valve. 

The spring-loaded pistons of the distributors 

can now deliver lubricant from the metering 

chambers to the lubrication points.

Piston distributors, group VKSO (relubrication distributors) 

VKSO2 VKSO4 VKSO6 

The distributors meter and distribute the 

lubricant from the pump to the individual 

lubrication points. They do so independent of 

each other. 

Interchangeable metering nipples make it 

possible to adapt the quantity to the amount 

of lubricant required by the friction point. 

The cycle number, i.e. the number of pump 

strokes per time unit of the lubrication 

system, also permits further coordination of 

the lubricant quantity with the friction point 

and entire system. 

Lubricant is only delivered under spring 

pressure after the end of pump operation, i.e. 

after the pressure is relieved.

closes the outlet to the lubrication point

via the lubrication points. 

For this purpose, distributors with horizontal

Operating instructions 

Open the grease drum and place the cover of the topping-up pump 

on the drum. Insert the suction tube in the opening in the cover, push 

down to the bottom of the grease drum and secure with the lock 

screw. 

Use a clean cloth to thoroughly clean the filler socket of the vehicle 

pump and filler coupling of the grease pump after removing the 

protective caps. Now connect the coupling of the topping-up pump 

to the filler socket of the vehicle pump. The hose coupling must snap 

into place when connected. 

Actuate the lever of the topping-up pump until the reservoir of the 

vehicle pump is filled to within approx. 1 cm of the top edge (max. 

marking on reservoir). 

When the reservoir is full, remove the coupling from the pump and 

put the protective cap back on the filler socket. Slip the coupling half 

of the topping-up pump onto the respective holder.

Connection of compressed air supply line to the compressed air system 

of a vehicle for a pneumatically operated centralized lubrication system 

• Observe the regulations of the German 

Technical Control Board (Technischer 

Überwachungs verein) when connecting the 

air supply for the centralized lubrication 

system. 

• The air supply line may only be connected 

to an air tank or to a line for secondary 

loads. 

• The compressed air for the centralized 

lubrication system must be clean and dry. 

The following check should be made to ascertain 

whether the air supply line has been 

connected at a place conforming to the safety 

regulations: 

Open the air line to the centralized lubrication 

system so that the air can escape. 

The air pressure indicated on the pressure 

gauge in the driver‘s cab must not drop 

below 5.5 bars; the airbrake pressure is thus 

maintained as prescribed.

Important product usage information 

All products from SKF may be used only for their intended purpose as 

described in this brochure and in any instructions. If operating instructions 

are supplied with the products, they must be read and followed. 

Not all lubricants are suitable for use in centralized lubrication systems. 

SKF does offer an inspection service to test customer supplied lubricant to 

determine if it can be used in a centralized system. SKF lubrication systems 

or their components are not approved for use with gases, liquefied gases, 

pressurized gases in solution and fluids with a vapor pressure exceeding 

normal atmospheric pressure (1013 mbars) by more than 0.5 bar at their 

maximum permissible temperature. 

Hazardous materials of any kind, especially the materials classified as hazardous 

by European Community Directive EC 67/548/EEC, Article 2, Par. 2, may 

only be used to fill SKF centralized lubrication systems and components and 

delivered and/or distributed with the same after consulting with and receiving 

written approval from SKF.
